Voice over Internet Protocol is a technology of transmitting voice on the Internet. Human voice is digitized, encoded, and transmitted on the Internet in the form of voice packets. These packets are received at the other end, decoded and converted back to analog signal. Loss and delay of voice packets result in the degradation of voice quality, since voice is a real-time application. Consecutiv...

Multiprotocol Label Switching (MPLS) is the latest technology in the evolution of routing and forwarding mechanisms for the core of the Internet. It ensures the reliable delivery of the Internet services with high transmission speed and lower delays. Traffic Engineering (TE) in MPLS is used for effectively managing the networks for efficient utilization of network resources. MPLS technology mak...

Voice communication is an emerging technology and has great importance in our routine life. Perceptual, Voice over Internet Protocol quality is an important issue for VoIP Apps services because VoIP Apps require real-time support. Many network factors (packet loss, packet delay, and jitter) affect to VoIP quality, to achieve this objective we used an approach based on Fuzzy Logic. We configure ...

The emergence of VoIP in the growing Internet services today has brought about new way in which services are rendered to the public. In viewofprovidingbetter alternative to Public Switch Telephone Network (PSTN) with high quality and efficient internet telephony (VoIP), there is a need of having an improved QoS in Voice transmitted over the Internet. In this work, the influence of different imp...
